Happens most often with rimfires that have been dry fired a lot. There were some old low value family guns with broken pins, a single shot 12 G among them. They'd been dry fired by two or three generations of kids I'm guessing. My brother and I hand-filed new pins for a couple of them and they worked pretty well until they finally gave up the ghost completely. My brother was working on a final-solution carbide pin for the shotgun (using a stud for a snowtire) but never finished it; I'd've loved to know if that would have worked out.
